T (UZz cpo'l'n.y it 11mg/ conccyzh'- l Beit knownthatl., CLEMENT L. REAMER, a citizen of the United States, residing at N ew.- ark,-in the county. ot' Licking and State of Ohio.. have invented a; new and useful Type- `Writer,ot' which the following is a specification.- 4 I i This invention .relates to certain improvements in type-writing machines, and has for its principal objectto increase'the rapidity of operation of ythe machine by permitting the operatortoprint-two characters at a single stroke and to allow.l double spacing at the end of a .word .or sentence. without the necessity of-Striliing-the spacing-key for each separate Spacing movement ofthe' cari'fiage.

l"ith these and lother objects in View the invention consists in the novel construction and combination of [parts hereinafter d escriblid,il li1stra ted in theaccompanying drawings. and particularly pointed out in the ap- ,pendrd claims. itheing understood that vairions changes in the form, proportions, and xninoiudetails' 't' coijilsti-nction mayY be made without#departing tromj the spirit or sacrilicinganyflftlie adrantages ot' the inventiovn.v ln the iliii\\irigs, Figure l 1s a longitudinal" sectional elevation of a type-writing machine constructed in accordance with the invention, unnecessary parts of the mechanism having been omitted in order to more clearly illustrate the construction. Fig. 2 is a rear elevation ofthe machine. Fig. 3 isadetail perspective view, partly in the nature of a diagram, illustrating the general arrangement ot' parts. Fig. el. is a rear elevation of an escapement mechanism constructed in accordance with the invention. Fig. 5 is a longiytudinal sectional elevation of the same on the lline 5" of Fig. 4. 'f

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

The frame 1 ot' vthe inachine,"which may be of the usual construction, is provided at the top with suitable rails for the transverselymovable carriage 2. carrying the impressionrack 4., with which intermcshes an escapement-controlled pinion 5 for permitting movement of the carriage at the conclusion of each v imprinting operation. f` l l lar to that in commercial use and known as the Smith Premier, wherein vertically-disposed tingcr-lceys, as 5'., are connected by rocker-arms to rock-shafts 7, which in turn are connected to type-carriers 8 by means of approximately vertical rods 9, so thai on the depression ol' a key the connected type-har will be operated and imprint the desired letter or character on the paper. In machines of the class it is usual to-cmploy a carriageactnatiug spring' tending' to draw the carriage to the left,` and a portion olf. such mechanism is shown at l() in Figs. 2 and 3, said mechanism being connected to the carriage by a flat band 12. formed of metal or other suitable material. ln the machines'of ordinary construction the downstrolie ot' the linger-key nieves an escapennent mechanisin to sncl'i position that after thel imprinting operation and portion ol' the paper at the imprintingpoint The machine shown in the drawings is simiplaten 3 and provided at its rear edge with a ythe release of the linger-key saidfescapement mechanism in reassumng its initial 'position y' fwillqperinit the carriage to travel to the extent lof a tooth or space, leaving a yblank "IOO in readiness for the next operation. This general mechanism being common to a numberv ofmachinesin commercial use is well known and does not require further detailed description.

liv-.the employment of the escapement mechanism hereinafter described each downstroke '.of one of the characterkeys 5 or similar single character or space keys I employ a second `set of keys, :as shown at 16 in Fig. 3, and an auxiliary double-space key 17, .the depression of any of these latter keys permit.

tinga movement of the carriage to the extent of two teeth or spaces. Each of the v doublecharacter keys, as they are termed for convenience, is connected to a type-bar 18, having its imprinting-type at a point one space to the rear of the usual printing-point, as shown in Fig. 3.

In practice the double-character keys may be of a number equal to the number of singlecharacter keysl 5', orthey may be so arranged as to provide only for the imprinting of a number of frequently-occurring characters, as ee, ss, 00, an, is, to,&c., and in addition4 to these a number of keys may be employed for the minor punctuationmarks-such as commas, semicolons, and colons-where each is followed by a space, s0 that the operator at a'single-stroke may print la multiple character or may print the desired punctuation-marks and at thesame time effect a double spacing, so that the writing of the nextgword may start without renderingit necessary to actuate the spacing key or bar. Where .the entire set of finger-keys is employed in the double-character arrangement, each will have buta single printing-type and this arranged one space to the rear of the im pression-point of. the single-character keys, so that any one Afinger-key of the double set may be simultaneously depressed with any one key of the single set to imprint any desired combination of characters. v

The escapement mechanism employed is best shown in Figs. 3, 4, and 5,1wherein the pinion 5, whiclrengages with the carriage-rack, is carried by a shaft 20, on which is secured a small wheel 21, connected by an intermediate gear 22 to a pinion 23 on the main shaft of the es-- capement mechanism.

The shaft 24 is mounted in a suitable bearing in a 'bracket 25 and at one end is provided with an escapement-wheel 26, having a peripheral ange27, on which are two sets of escapement-teeth equalin number and when actuated Vpermitting movement of said shaft to an equal'extent.y The radiating teeth 28 are engaged 'by vpallets formed at the ends of an anchor 29, "which is operated after the manner of al dead ,-,beatescapement-anchor,

having its depending-arm 31 connected to va rock-shaft 32, carrying rocker-arms 33 of a number proportioned to the number of singlecharacter keys. The single-character keys, as well as the single-space keys, are connected by their individual rock-shafts' and rockerarms to the arm or arms 33 of the main rockshaft 32, the connection being in the form of slotted links or bars 34, which will permit a single-character keys 5'` or on'the single-space' keys 115 will result in the usual printing operation inthe case of the vcharacter-keys and at the same time the shaft 32 will be rocked to an extent suiicient to move the pallet 36 out of engagement with one of the escapementmeti/1,28 and to move the'opposite pallet, 37, into engagement with another of said teeth. This occurs during the imprinting operation.

, and without permitting any movement of the carriage. .When the key is released and the parts are returned to position by the spring or other mechanism employed for this purpose,A the pull of the carriage-spring will force'the pallet 37 outward, while a spring 38, arranged under the anchor, will assist this movement and release the escapement-wheel,

so that the latter may rotate to the extent of a single tooth before it is caught by the pallet 36. Thisl movement is transmitted from the carriage through the several gear-wheels.

On the annular face of the flange 27 are crown escapement-t'eeth 40, with which may engage controlling devices represented in the present instance by a diametral escapementbar 41, pivoted between the spaced lugs of a small bracket 42, which projects from anescapement-disk 43, arranged within the Hange 27. The longer end of-the diametralescapement-bar is normally in engagement with one of the crown-teeth, being held in this position by a small compression-spring 44, extending between the escapement-bar and the disk 43, and said disk 43 is secured to or formed integral with a hollow shaft 45 constituting thev main shaft of thel escapement, and provided at its opposite end with they small pinion 23. The shaft 45 is hollow and receives a longitunally-movable spindle 48.r The spindle 48A bears at one end against `the central vportion of the escapement-bar `41 and at its opposite end is engaged by a rocker-arm 49, so that when moved in the direction of the escapement-barthe longer arm of the latter will be moved out of vengagement with one of the crown-teeth, while the shorter arm will be moved into engagement with a diametrically opposite tooth without, howeverpermitting rotative movement of lthe ratchet-wheel.

IOO

IIO

Extending transversely of the rear portion of the machine is a rock-shaft 50, carrying the rockersarm 49 and provided With a plurality of rocker-arms, as 51 52, and a central rockerarm 53, the latter being connected by a slotted link 54 to a rocker-arm 55, carried by the.

main rock-shaft 32.

The seveial double-character keys 16`are carried by rock-shafts7' and near their rear ends have rocker-arms 54', which are connected by slotted links 55' to the rocker-arms 51', projecting from rock-shafts 50. In similar manner the rock-shaft of the double-spaced key 17 is connected by a rocker-arm 57 and slotted link 58 to the rocker-arm 52 on shaft 50.

When a double-space key 17 or a doublecharacter key-is depressed, the movement is imparted first through one or other`of the links and rock-shafts to rock-shaft and thence by rocker-arm 49to the spindle 48. This results in an outward movement of escapenient-bar 41, moving the longer arm of the latter out of engagement with one of the crown-teeth and the shorter arm of said bar into engagement with a diametrically opposite tooth. During this movement the connection between the `rock-shaft 50 and rockshat't 32 through arms 53 and 55 and link 5 4 causes the previously-described preliminary movement of the anchor 29, the pallet 37 moving into engagement with one of the radial teeth 28, while the mating pallet moves out of engagement with a corresponding tooth.

rlhe printing operation takes place during the downward movement ot' the key oi' keys, and as the imprinting-type of the double-character keys are arranged at a point to the rear of the imprinting-point of the single-character keys one of each set may be operated to print any desired combination of characters. On the release of the key or keys the anchorescapement acts first and permits rotative movement of the escapement-wheel 25, this quick movement being transmitted through one of the crown-teeth and the shorter arm of the escapement-bar 4:1 "to the disk 43 and thence to the gearing.

. has nearly resumed its initial position, the

spindle 4.8 has been forced inward or in the direction of the keyboard under the intluence of spring 44, and as the shorter arm of the escapement-bar moves from engagement with its tooth the longer arm arrives at initial position in time to catch the next succeeding tooth, so that at the completion of the operation the carriage has been moved two spaces.

The number of escapements vmay be increased in order to permit spacing movement to the extent of two, three, or more teeth, desired, in order to properly space between sentences at a single stroke, or a third or fourth set of keys may be employed having an imprinting-point at the proper distance from the normal in` order' to provide for the When the iinger-key characters.

The arrangement in the presentinstance permits the printing of any two characters or simultaneous printing of three or four or more the printing of a single character or piinctuaf double spaces,lby the depression proper l,

keys.
